Okay, this is gonna be a bit embarressing ...but...I did not read the instructions to the ammonia test properly. That is because and only because I am an idiot. Now there are 2 test bottles not the 1 in the API master kit. Please read the statement above...I am an idiot. The bad news is I have let everyone on the forum know how stupid I am. The absolutely great news is my ammonia level is detectable at somewhere between 0.5 and 1. I think at a guess I would say 0.75. So the prawn is producing ammonia.
So as a precautionary measure I decided to test nitrites...and yes i read the instructions and there is only 1 bottle to use. Surprisingly there was a very slight hint that nitrites were also forming. By the colour I would say under the 0.25 mark.
Since I tested all that. I tested the nitrates as well.
So In summary after 24 hours we have:
Ammonia 0.75
Nitrites 0.15
Nitrates 0.00
Will test again in 12 to 24 hours.
